VvBACK- BAND BUCKLE.

SPECIFICATION forming part of Letters Patent No. 538,059, dated April 23, 1895.

Application filed February 5, 1895. Serial No. 537,362. (No model.)

To all whom t may concern.-

Be it known that I, WALTER F. ANTHONY, a citizen of the United States, residing at Williamsport, county of Lycoming, and State of Pennsylvania, have invented certain new and useful Improvements in Back-Band Buckles, of which the following is a specification.

The invention relates to such improvements and consists of the novel construction and combination of parts hereinafter described and subsequently claimed.

Reference maybe had to the accompanying drawings, and the letters of reference marked thereon, which form a part of this specification.

Similar letter refer to similar parts in the several figures therein.

Figure l of the drawings is a top plan view of my improved buckle. Fig. 2 is a central longitudinal vertical section of same taken on the broken linev2-2, in Fig. 1', showing the buckle attached to the webbing. Fig. 3 is a similar section showing a modification of the hook and the wedge-piece lever swung out to open the hook.

My improved buckle is preferably made of sheet-metal, cut and swaged by suitable dies, although some or all the parts maybe formed of malleable castings.

I have shown in the drawings my improved buckle made of two pieces of sheet-metal. One part comprises the web-plate A-' having the transverse web-slots A- and A2, the bearing-lugs AS- and A4 bent up from the opposite sidesy of the plate and containing bearing-apertures A5 and the depending hook B-. The other part comprises the wedge-piece C-having the teeth O- adapted to engage the webbing W- and pivots or trunnions C2. and (3B-adapted to enter the bearing apertures, and the lever O4 for operating the wedge-piece. The depending hook B is adapted to receive one of the links of a trace-chain and thereby support the chain. The upper end of the hook is provided with an inwardly projecting offset B -which partially closes the hook-opening and reduces the liability of the link to accidental-ly escape from the hook. As a further means for guarding the hook-opening against the accidental escape of the link, I provide the Wedge-piece lever with an offset O5- which projects out- .wardiy over the mouth of the hook-opening and occupies a position approximately parallel with the odset on the hook, when the buckle is in use. The two offsets are separated from each other` by a small space sufficient to permit of the free operation of the lever, but less in width than the diameter of the wire forming the link. The outer end of 6o the offset C5 is provided with an upwardly projecting offset C6- serving as a catch or handle in operating the lever to loosen the grip of the wedge-piece upon the webbing, and

to open the hook for the insertion or removal of the chain-link, as shown in Fig. 3. The pressure of the webbing upon the toothed end of the wedge-piece holds the oiset on the lever in the proper position to close the hookopening, the lever resting upon the webbing, 7o

as shown lin Fig. 2.

When desired, the offset on the hook can be made to project downwardly as well as inwardly, as shown in Fig. 3, whereby the link is prevented from slipping off the,hookoffset 75 B2- to engage the lever-offset. By projecting the lever-odset at right angles to the plane of the body-part of the buckle, 'the pressure of the link u pon such offset does not tend to loosen the wedge-piece, but ratherto 8o secure it more tightly, because the contracted hook-opening through which the link must pass to engage the lever-offset is located nearer the plane of the body part of the buckle than is the axial line of the wedgey piece, so that the upward pressure of the link, while in the contracted hookopening upon the lever-offset, tends to force the lever more closely against the web instead of out away from the web, thereby affording a cer- 9o tain guard or lock for the hook-opening. By means of the handle-offsets C5- and O6- the lever can be easily operated to open the hook or to adjust the buckle upon the webbing.

The lower web-slot which neighbors the hook,

IOO

to readjust the position of the buckle on the webbing.

That I claim as new, and desire to secure by Letters Patent, is-

l. In a back-band buckle, the combination with an ntxoverted offset on the upper end of the hook, of an offset on the wedge-piece lever projecting outwardly over the mouth of the hook and closing the mouth opening, substantially as described.

2. In aback-band buekle,havingon its Webplate a depending tracehook, a wedge-piece having the end of its operating lever bent outwardly and upwardly by successive offsets, whereby the first offset serves as a guard 15 for the mouth of the subjacent hook, and both offsets aord a convenient lever-operating handle, substantially as described.

In testimony whereof I have hereunto set my hand this 24th day of January, 1895.
